Patrick had the ability to leave his body and go into somebody else's.
He mainly used it to take over some of his male neighbours and sleep with their wives.
One night he tried it the other way around and found he much preferred it being the woman.
He tried every woman in the neighborhood 3 or 4 times before he found the one he loved the most to be in.
Sandra was in her 40s big breasted and bubbly just the sort of woman he loved.
He loved being in her body so much that he decided to make it a permanent thing.
So he returned back to his body signed all his possessions over to her in the event of his death with a million-dollar life insurance policy
Then he returned to her body and got himself Knocked Up in her body making the swap permanent which caused his old body to die of a massive heart attack.
